Abstract(in English) | A sensor circuit based on a relaxation oscillator has merits such that a sensor signal can be easily digitized using a counter and resolution can be varied according to the measurement time of a counter. In order to operate this circuit with sub-μW consumption, low power consumption of a comparator that consumes steady current is a problem. Since the response time of the comparator is getting worse due to low power consumption, in the sensor circuit based on a relaxation oscillator using this, the problem is that the measurement accuracy is getting worse. In this research group, we are developing an oscillator type sensor circuit using 180 nm Si CMOS process, but in this paper we investigated the use of 65 nm Si CMOS process to improve response speed . As a result of analysis by circuit simulation,in the case of aiming for sub-μW class operation, it was found that when using a relatively fine transistor, it may not operate properly due to the influence of gate leak. |
